The efficacy of the A. sisalana extract in the LDT ranged from0% to 100%.
The highest concentrations (0.06–1 mg/mL) differed statistically fromthe lowest ones (0.007–0.03 mg/mL).
No L3 were observed at concentrations of 0.12–1 mg/mL, demonstrating larvicidal action.
The average inhibition percentage in the LDT in the negative control was 13.2% (Table 2). The LC50 and LC95 in the LDT were 0.041 (0.034–0.049) and 0.067 (0.055–0.099) mg/mL, respectively (Fig. 3).
The feeding inhibition after 2 h of exposure of the L1 to the treatments ranged from 0% to 100%. At the four highest
